Data visualization involves the creation and study of the visual representation of data which helps to communicate information clearly and efficiently.

Most of the time, developers will suggest Matplotlib, Plotly or Seaborn. Today, I would like to introduce a package called Altair. It is a declarative statistical visualization library for Python based on Vega and Vega-Lite.

With Altair, you can build heatmap, stacked bar or area chart easily with guidance of example codes.
